collectDescendantsOfType

inline fun <reified T : PsiElement> PsiElement.collectDescendantsOfType(noinline predicate: (T) -> Boolean = { true }): List<T>

Collects this element and all descendants of type T satisfying predicate into a list in post-order.

inline fun <reified T : PsiElement> PsiElement.collectDescendantsOfType(crossinline canGoInside: (PsiElement) -> Boolean, noinline predicate: (T) -> Boolean = { true }): List<T>

Collects this element and all descendants of type T satisfying predicate into a list in post-order. canGoInside controls traversal into children but does not prevent the current element from being collected.
